AD5662WARMZ-1REEL7

Overview

The AD5662WARMZ-1REEL7 is a single-channel, 16-bit buffered voltage-output digital-to-analog converter (DAC) from the nanoDAC family. It operates on a single 2.7 V to 5.5 V supply with typical current consumption of 250 μA at 5 V. The device features rail-to-rail output swing and an external reference input. It incorporates a power-on reset circuit that initializes the output to zero scale upon startup. The part utilizes a versatile 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards, supporting clock rates up to 30 MHz.

Feature Summary

• 16-bit resolution with guaranteed monotonicity by design
• Power-on reset to zero scale for AD5662x-1 variants
• Rail-to-rail output amplifier with remote sensing capability via VFB pin
• Three software-selectable power-down modes reducing current to 480 nA at 5 V

Applications

• Process control systems
• Portable battery-powered instruments
• Programmable voltage and current sources
• Digital gain and offset adjustment circuits

Procurement Notes

Verify the specific suffix '1' in the part number AD5662WARMZ-1REEL7 against official documentation to confirm the power-on reset behavior corresponds to zero scale initialization. Ensure the ordering suffix matches the required package type and temperature grade specified in the manufacturer's ordering guide.

Selection Notes

Select this component when a single-channel, high-resolution DAC with low power consumption is required. The external reference input allows flexibility in setting the output range. Verify that the system interface supports the 3-wire synchronous protocol and that the operating temperature range of -40°C to +125°C meets environmental requirements.

Part Context

This device belongs to the AD5662 nanoDAC family, which includes variants with different power-on reset behaviors and packaging options. The 'WARMZ' designation indicates an MSOP-8 package variant, while the '-1' suffix specifies the zero-scale power-on reset function. Other family members may offer internal references or dual-channel configurations.

Replacement Considerations

Direct replacements within the same family include AD5662ARJZ-2REEL7 and AD5662BRMZ-1REEL7. Note that the '-2' suffix variants initialize to midscale rather than zero scale. Ensure the replacement part matches the required reset state and package dimensions for PCB compatibility.
